Welcome to Game World . What can I do for you ?   I'd like to get a good RPG . Can you recommend any ?   Sure . This one here just came out . It's got great 3D graphics and a cool story line . It's also got a multiplayer function so you can play against other people on the Internet .   This one looks pretty good , but I'd like to see more before I make up my mind . Do you have any other suggestions ?   This one is also really cool . It's a sci-fi game in which you have to stop an alien invasion . The graphics on this one are spectacular .   Hmm , it's a tough choice , but I think I'll go with this one .
